707Ex mA Calibrator
Introduction WWarning
Read Safety Information before you use the Calibrator.
The Fluke 707Ex mA Calibrator (hereafter, "the Calibrator") is a compact and easy to operate sourcing and measuring tool. The Calibrator tests current loops of 0-20 mA or 4-20 mA and measures dc voltage to 28 V. It comes with a set of alligator-clip test leads, a 9 V alkaline battery installed, and this Users manual on a CD.
The Calibrator is ideal for use in confined and restricted spaces within Ex-hazardous areas according to IEC/CENELEC and Factory Mutual.

Battery Saver The Calibrator automatically turns off after 30 minutes of inactivity. To reduce this time or disable this feature:
1. With the Calibrator OFF, press D.
P.S. xx is displayed, where xx is the turn-off time in minutes. OFF means the power saver is disabled.
2. Turn k to decrease or lto increase the turn-off time.
To disable, turn k until the display shows OFF.
3. The Calibrator resumes normal operation after 2 seconds.
Safety Information In this manual a Warning identifies conditions and actions that pose hazards to the user. A Caution identifies conditions and actions that may damage the Calibrator or equipment under test. International symbols used in this manual are identified later in the Symbols section.
Read the entire Users Manual and the 707Ex mA Calibrator CCD (Concept Control Drawing) before using the Calibrator.
WWarnings and Cautions To avoid electric shock, injury, or damage to the Calibrator: • Use the Calibrator only as described in this
Users Manual and the Fluke 707Ex mA Calibrator CCD (Concept Control Drawing) or the protection provided by the Calibrator may be impaired.
• Inspect the Calibrator before use. Do not use it if it appears damaged.
• Check the test leads for continuity, damaged insulation, or exposed metal. Replace damaged test leads.
• Never apply more than 28 V between the input terminals, or between any terminal and earth ground. Applying more than 28 volts to the input terminals invalidates the Calibrator’s Ex Approval and may result in permanent damage to the unit so it can no longer be used.
• Use the proper terminals, mode, and range for your measuring or sourcing application.
• To prevent damage to the unit under test, put the Calibrator in the correct mode before connecting the test leads.
• When making connections, connect the COM test probe before the live test probe. When disconnecting, disconnect the live probe before the COM probe.
mA Calibrator Safety Information

• Never use the Calibrator with the red holster removed.
• Never use the Calibrator with the case open. Opening the case violates Ex Approval
• Make sure the battery door is closed before you use the Calibrator.
• Replace the battery as soon as the M (low battery) symbol appears to avoid false readings that can lead to electric shock.
• Remove test leads from the Calibrator before opening the battery door.
• This equipment is specified for use in measurement category I (CAT I) pollution degree 2 environments and should not be used in CAT II, CAT III, or CAT IV environments. Voltage transients should not exceed 300 volts for the CAT I applications where this product is used. Measurement transients are defined in IEC1010-1 as 2 μs rise time with a 50 μs duration at 50 % of the maximum amplitude height.
• Measurement Category I (CAT I) is defined for measurements performed on circuits not directly connected to the mains.
• Do not use in a damp or wet environment.
Safety Advice To ensure safe operation of the Calibrator fully observe all instructions and warnings contained in this manual. In case of doubt (due to translation and/or printing errors) refer to the original English manual.
Faults and Damage Applying a voltage greater than 28 V to the input of the Calibrator invalidates its Ex Approval and may impair its safe operation in an Ex-hazardous area.
If there is any reason to suspect that the safe operation of the Calibrator has been affected, it must be immediately withdrawn from use, and precautionary measures must be taken to prevent any further use of the Calibrator in an Ex-hazardous area.
The safety features and integrity of the unit may be compromised by any of the following: • External damage to the housing • Internal damage to the Calibrator • Exposure to excessive loads • Incorrect storage of the unit • Damage sustained in transit • Correct certification is illegible • Using the product with the red holster removed • Functioning errors occur • Permitted limitations are exceeded • Functioning errors or obvious measurement
inaccuracies occur which prevent further measurement by the Calibrator

Safety Regulations The use of this 707Ex mA Calibrator meets the requirements of the regulations providing that the user observes and applies the requirements as laid down in the regulations and that improper and incorrect use of the unit is avoided. • Use must be restricted to the specified application
parameters. • Do not open the Calibrator. • Do not remove or install the battery within the
Ex-hazardous area. • Do not carry additional batteries within the
Ex-hazardous area. • Use only type-tested batteries. The use of any other
battery will invalidate the Ex-certification and present a safety risk.
• Do not use the Calibrator in an Ex-hazardous area unless it is completely and securely fitted in its accompanying red holster.
• After using the Calibrator in a non-intrinsically safe protected circuit, a rest time of 3 minutes minimum duration must occur before the Calibrator is taken into and/or used in an Ex-hazardous area.

Using the mA Sourcing (Output) Modes The Calibrator outputs current for calibrating and testing 0 to 20 mA and 4 to 20 mA current loops and instruments.
In SOURCE mode, the Calibrator supplies the current.
In SIMULATE mode, the Calibrator simulates a 2-wire transmitter in an externally powered current loop.
Changing the mA Output Span The Calibrator has two mA output spans:
• 4 mA to 20 mA (0 % to 100 %) [default]
• 0 mA to 20 mA (0 % to 100 %) [optional]
To change the output span, turn the Calibrator off. Press A + D simultaneously. The selected setting is saved until it is changed again.
Sourcing mA Use SOURCE mode to supply current to a passive circuit.
A path must exist for current to flow between the + and the COM terminals. Otherwise, the display flashes when you set an output value.
